Just received a Freud SD 508 stacked dado set. I just barely was able to mount enough chippers and the two outside blades on the arbor then add the flange and nut For a 3/4" cut. What I got is a 10" 3HP Unisaw (36-820). Whew! The nut just has enough thread left to tighten up the stack. I mean barely. I can still feel a slight depression where the opening to the nut comes on contact with end of the arbor. Is my experience 'typical' for this size saw?
